Final answer:
The initial management step for FHR deceleration involves changing the maternal position to alleviate any potential pressure on the umbilical cord or improve blood flow, which may resolve the deceleration. Subsequent steps include administering oxygen, starting IV fluids, and performing a vaginal examination.
Step-by-step explanation:
The first step in managing a Fetal Heart Rate (FHR) deceleration is to change the maternal position. This action can relieve pressure on the umbilical cord or improve uteroplacental blood flow, potentially resolving the deceleration. Subsequent interventions can include administering oxygen to the mother, starting intravenous fluid infusion, and performing a vaginal examination to assess the situation further. However, the initial change in maternal position is a non-invasive and immediate measure that can be critical in situations of FHR decelerations. It is essential to understand that each contraction reduces oxygenated blood flow to the fetus, and fetal distress can result from contractions that are too strong or long without adequate relaxation periods, requiring emergent delivery methods if not resolved.
